An experiment to use Microbits to control MIDI devices.
One Microbit acts as a receiver for others that transmit values over radio. It relays these to the serial bus (USB)
These are picked up by a Ruby programme and converted to MIDI controller values hardcoded for a Novation Bass Station synth and sent
You need 2 of these.
Paste the code for the Transmitter into the editor and download this to your Microbit.
Repeat for the Receiver and leave this one connected. Connect the Transmitter to a set of batteries.
Run cd ruby && bundle install to add the required Gems.
In the ruby directory, run ruby src/microbit-reader.rb and chose a MIDI output (you need one of these). If you move your Transmitter Microbit around, it will output the values it maps to the MIDI controllers and send to your synth.
- Make the buttons and gestures do something.
- Make synth agnostic (configurable mapping of controls, e.g. 'learn')
- Allow ranges to be set for controllers, e.g. so we can restrict resonance, etc.
- Make Microbit transmit without 'throttling' - do this in the ruby code (was done to reduce sensitivity)
